金属酞菁(PC)由于其独特的光吸收性能和对化学和热分解的高度稳定性，在颜料、滤色器、光伏器件和非线性光学等领域具有广泛的应用前景。金属PC的纳米晶(NCS)由于将晶体尺寸减小到纳米级可以显著提高金属PC的光学和电学性能，因此受到人们的广泛关注。在这项研究中，我们展示了在纳米胶束中通过紫外光照射前驱体直接合成铜和锌的PCS。通过添加聚乙二醇作稳定剂，将合成的金属PC纳米管稳定地分散在水中。PC-NCS的水分散体在500~800 nm范围内表现出较强的可见光吸收，在非吸收区域具有较高的透光率。
Metal phthalocyanines (PCs) are promising materials for various applications, including pigments, color filters, photovoltaic devices, and nonlinear optics, owing to their specific light-absorption properties and high stability to chemical and thermal degradation. Nanocrystals (NCs) of metal PCs have received much attention because the optical and electronic properties of metal PCs are improved considerably by decreasing the crystal size to the nanoscale. In this study, we demonstrated the direct synthesis of Cu and Zn PCs in nanosized micelles by irradiating precursors with UV light. The synthesized metal PC NCs were stably dispersed in water by adding polyethylene glycol as a stabilizer. The aqueous dispersions of PC NCs showed strong visible light absorption from 500 to 800 nm and high transparency at wavelengths in the non-absorption region.
